Application led October 13, 1924. Serial No. 743,374. Y

My invention relates to a smoke condenser and my 'object is to providean'eiiicient apparatus of this character which may e economicallyemployed for condensing lsmoke emitted by domestic and industrial lfurnaces. y

A further ob'ect is to provide van apparatus which wil create a draftthrough the furnace and dis ose of the gases and other products of comustion. 4

Inorder that the invention may be fully understood, reference will nowbe had to the accompanying drawings, in which:

Fig. 1 is a side elevation of the apparatus. Fig. 2 isa vertical sectionofthe'apparatus. Fig. 3 is a detail sectional view of a steam nozzleemployed in 'carrying out the invention. Fig. 4 is a detail sectionalview of a water nozzle employed in carrying out the invention.

Referring npw in detail to the diii'erent parts, 2 desi ates a casingwhich is erably cylin rical in cross section and as a base portion 4 anda removable cap 6.

The lower portion of the casing 2 is provided with a transversepartition 8 having a central outlet 10 communicating with a trap 12depending from said partition 8 and provided with a drain pipe 14leading to the lexterior of the casing 2.

16 designates an open mesh tray arranged Within the casing 2 at asuitable distance above the partition 8 for holding a filteringl agent,such for instance as coke.

18 designates a baffle arranged within the casing 2 at a suitable pointabove the tray 16, and 2() designates another baille spaced.

above the bailie 18.

22 designates an inlet pipe which may be connected to the smoke pipe ofa furnace. Said inlet. pipe 22 communicates with the chamber 24 formedby the casing 2, the partition 8 andthe tray 16. y

26 designates a steam nozzle arranged in the lower portion of :theinlet. pipe 22 and provided with a spreader v28.` :Said steam nozzle 26-is connected to a suitable source of sup ly, notv shown, through theinterme iacy of a steam pipe 30.

32 desi in the chamber 24 for directin a mist towards the lower end ofthe in et pipe 30. Said nozzle 32 is connected to a suitable source, notshown, through the intermediacy of a water pipe 34 which has a branch 36refy ates a water nozzle located with-1 leading to a nozzle 38 located1in Athe cap 6. Valves 40, 42 and 44 provide means for independentlycontrolling the flow of steam to the nozzle 26, and water to the nozzles32 and 60 38, respectively, sothat the sup ly to an one may be cut offwithout inter ering witii the supply to the others.

46 designates an outlet pipe leading from the cap 6 and connected to asuction fan 48. 65

The casing 2 is provided with doors 50, 52, 54 and 56, so that accessmaybe readily had t'o the trap 12, the chamber 24, the tra)v 16, andthenozzle 38, respectively.

In practice the inlet pipe 22 is connected 7" to the smoke pipe of afurnace after the tray 16 has been supplied with a filtering agent. Thefan 48 isthen set in motion for creating a draft through the casing 2and drawing the smoke from the furnace. As the smoke is about to enterthe casin 2 from the inlet pipe 22, it is sprayed with steam from thenozzle 26 and with water from the nozzle 32. This combination f spraysprecipitates the carbon and other unconsumed 30 solids Vof the productsof combustion upon the partition 8, from which it is `Washed into thetrap 12 and escapes through the drain 14. Said combination of spraysalso dissipates' the obnoxious gases present in the 85 products ofcombustion. Any remaining products of combustion are drawn upwardly ythe suction fan 48 through the filtering .the lteringla-gent may eremoved through thewdoor 54v and cleansed for reuse, or a new supply maybe provided as found necessary or desirable.

From the foregoing description it is apparent that I have l.provided asmoke conenser embodying the advantages above pointed out, and while Ihave shown and` described the preferred construction, combi- `-110nation and arrangement of parts I reserve the right to make such changesas properly assaut-n. l

fall within the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim and desire to secure byLetters Pat- 5 ent, is

An apparatus of the character described consisting of a casing having aninlet, a removable cap to said casing having an outlet, means connectedto said outlet for creating 10 a draft through the casing, a partitionarranged in the casing. at a point below the inlet, a drain leading fromsaid partition, an o en mesh tra within the casing and spaced a ove thein et, superimposed battles arranged in the casing above said tray, asteam nozzle arranged in the inlet, a water nozzle arranged inthe-*casing and directed towards the inletg and a water nozzle arrangedin said cap, substantially as shown and described.

In testimony whereof I atlix m signature.

WILLIAM W. RO INSON.
